Abstract
To set a shading relationship between the plurality of shading inks having the same system color and different densities included in a plurality of kinds of inks, to perform provisional color separation processing to decide a color space value in a virtual color space in the second color system for every lattice point that defines a correspondence relationship between the first and second color spaces, to perform first processing of setting a position of the lattice point where a generation amount of the first ink at the lattice point can be maximized and an ink amount at the lattice point for a first ink which is one of light inks from a result of the provisional color separation processing, and then to perform second processing of setting an ink amount of the first ink and an ink amount of a second ink having a higher density by giving priority to a use of the first ink while maintaining a virtual color space value of the provisional color separation processing result for the first ink.
